<title>fraction.js - a javascript fraction library</title>

<h1>fraction.js</h1>

<div>
    <em>fraction.js</em> is a fraction library written in javascript.  With it
    you can comfortably create and manipulate fractions from Javascript.
</div>
<p>
<div>
Usage:
<pre>
js> load('fraction-0.2.js'); // creates the global Fraction object
<span id='examples'>
js> (new Fraction(7,3)).multiply(new Fraction(1,2))
1 1/6
js> (new Fraction(7,3)).divide(new Fraction(1,2))
4 2/3
js> (new Fraction(3,10)).add(new Fraction(5,9))
77/90
js> (new Fraction(0.25)).add(new Fraction(1,6))
5/12
js> (new Fraction(0.35)).subtract(new Fraction(1,4))
1/10
</span>

    <h3>Notes</h3>
    <ul>
        <li>Each Fraction object contains two members: denominator and
        numerator.</li>

        <li>Fractions are stored following all operations in normalized
        (numerator and denominator are divided by their greatest common
        factor).</li>

        <li>Fractions methods can take any type of number or other
        fractions objects.</li>

        <li>Fractions can be created from any kind of number (e.g. f = new
        Fraction(0.25) yields '1/4'), although rounding problems in Javascript
        may produce unintended results if fractions are initialized with the
        decimal equivalents of numbers such as 1/3, 1/9, etc.</li>

    </ul>
